If the value of equilibrium constant for a particular reaction is 1.6 $$ \times $$ 10¹², then at equilibrium the system will contain

Which of the following statements is correct for a reversible process in a state of equilibrium?

For the reversible reaction,
N_2(g) + 3H_2(g) $$\rightleftharpoons$$ 2NH_3(g) + heat

The equilibrium shifts in forward direction

Using the Gibb's energy change, $$\Delta $$G^o = +63.3 kJ, for the following reaction,

Ag₂CO_3(s) $$\rightleftharpoons$$ 2 Ag⁺_(aq) + CO₃^2$$-$$ _(aq)
the K_sp of Ag₂CO_3(s) in water at 25^oC is
(R = 8.314 J K^$$-$$1 mol^$$-$$1)
